Acute Care CNA Exam study guide
UPDATED ACTUAL Exam Questions and
CORRECT Answers
Emphysema - CORRECT ANSWER - A chronic lung condition where alveoli are
damaged, leading to difficulty in breathing. Causes include smoking and long-term exposure to
pollutants.
Pleural Space - CORRECT ANSWER - The area between the lungs and chest wall that
contains fluid to reduce friction during breathing.
Precautions for COVID-19 - CORRECT ANSWER - Standard precautions include
wearing PPE, hand hygiene, and maintaining isolation protocols for infected patients.
COPD (Chronic Obstructive Pulmonary Disease) - CORRECT ANSWER - A progressive
lung disease that includes emphysema and chronic bronchitis. Care involves oxygen therapy,
bronchodilators, and pulmonary rehabilitation.
Pneumothorax - CORRECT ANSWER - A collapsed lung due to air entering the pleural
space. Treatment includes chest tube insertion to remove trapped air.
Healthy Lung Tissue - CORRECT ANSWER - Pink, elastic, and well-vascularized tissue
that efficiently exchanges oxygen and carbon dioxide.
Lung Function & Gas Exchange - CORRECT ANSWER - The lungs oxygenate blood and
remove CO₂. Gas exchange occurs in the alveoli.
Patients Affected by TB - CORRECT ANSWER - Immunocompromised individuals,
those in crowded living conditions, and healthcare workers are at higher risk.
, Gangrene - CORRECT ANSWER - Tissue death due to lack of blood supply, often caused
by infection or diabetes.
Drainage Tubes in Wounds - CORRECT ANSWER - Used to remove excess fluid and
prevent infection.
Metastasis - CORRECT ANSWER - The spread of cancer cells from the primary site to
other parts of the body.
Diagnostic Tests (MRI, Scans, Biopsy) - CORRECT ANSWER - Used to detect tumors,
assess spread, and confirm cancer type.
Immune System Decline in Cancer Patients - CORRECT ANSWER - Chemotherapy and
radiation weaken immunity.
Importance of Check-ups - CORRECT ANSWER - Early detection improves treatment
outcomes.
Causes of Brain Damage - CORRECT ANSWER - Stroke, trauma, tumors, and infections.
EKG Purpose - CORRECT ANSWER - Measures electrical activity of the heart to
diagnose arrhythmias and heart conditions.
Heart Muscle & Chest Pain - CORRECT ANSWER - The myocardium is affected in
angina and heart attacks.
Hypertension (HTN) - CORRECT ANSWER - High blood pressure that increases the risk
of heart disease.
Heart Failure Treatment - CORRECT ANSWER - Includes diuretics, ACE inhibitors, and
lifestyle changes.
